Chronic daily headache has been classified into several categories. One category is of sudden onset and is called New Daily Persistent Headache (NDPH). Another category of daily headache evolves gradually and is called Transformed Migraine (TM). This research study is being conducted to compare people with these two kinds of daily headache in order to improve our understanding of these conditions.
